415 | support.h so that, like cpu, it is optionally inlined for all | |
416 | modules that include it. | |
417 | * inline.h, inline.c: Adjust so that support.[hc] is handled the | |
418 | same as cpu.[hc]. | |

427 | Wed Jul 24 14:02:42 1996 Andrew Cagney <cagney@sawnoff.highland.com.au> | |
428 | ||
429 | * gen-idecode.c (print_run_until_stop_body): Too many rparen in | |
430 | generated code. | |
431 | ||
432 | Tue Jul 23 20:57:01 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
433 | ||
434 | * configure.in (--enable-sim-line-nr): Typo - sim_line-nr. | |
435 | * (--enable-sim-inline): Reorder patern matching of arguments so | |
436 | that SUPPORT=ALL_INLINE is reconized as *=* and not *_INLINE. | |

439 | ||
440 | Mon Jul 22 23:25:08 1996 Andrew Cagney <cagney@highland.com.au> | |

442 | * configure.in (--enable-sim-hardware, --enable-sim-packages): New | |
443 | configuration options. Let the user specify the packages or | |
444 | hardware devices that are to be included in the build. Makes it | |
445 | possible for user packages to be specified. | |
446 | ||
447 | * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and | |
448 | hardware instead of checking it using ls. configure.in should | |
449 | have taken care of any problems. | |

451 | ||
452 | Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au> | |
453 | ||
454 | * psim.c (psim_options): Enter the argument to the memory size | |
455 | option directly into the device tree. Was using atol() which is | |
456 | dangerously non portable. | |
457 | ||

459 | ||
460 | * configure.in (icache): Extend icache flag to include an insn | |

485 | * gen-semantics.c: Make the my_index variable a macro MY_INDEX. | |
486 | ||
487 | * ppc-instructions: Adjust so that references are to MY_INDEX and | |
488 | not my_index. | |
489 | ||
490 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
491 | ||
492 | * gen-idecode.c: Output the complete run_until_stop function | |
493 | instead of just the code to handle a single instruction issue. | |
494 | * : Have the generated idecode.c include inline.c (instead of psim.c). | |
495 | ||
496 | * std-config.h: Change psim.c so that it isn't inlined (as this is | |
497 | no longer needed). | |
498 | ||
499 | * psim.c (run_until_stop): Delete the old run_until_stop function | |
500 | instead calling the idecode_run and idecode_run_until_stop | |
501 | functions that gen-idecode.c is now creating. | |
502 | ||
503 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
504 | ||

513 | eliminate trace statements. | |
514 | ||

519 | source line number to the instruction's informational entry. | |

522 | current instructions name and source line number. | |
523 | ||
524 | * gen-semantics.c, gen-icache.c: Adjust generated ITRACE calls to | |
525 | match new interface. | |

528 | corresponding call to ITRACE so that it still matches. | |
529 | ||
530 | * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead | |
531 | of ITRACE. The CPP line directives would have previously set the | |
532 | line-nr and file name so ITRACE isn't needed. | |

535 | ||
536 | * gen-idecode.c (print_jump_until_stop_body): New function and | |
537 | idecode generation option. Instead of generating and calling | |
538 | separate functions containing the semantic and icache code | |
539 | generate a single monolythic function and use goto's (and GCC's | |
540 | indirect jump) to move between code blocks. | |
541 | ||
542 | * Makefile.in: Add sim_jump flag to those passed to igen. | |
543 | ||
544 | * configure.in: New option --enable-sim-jump (default disabled) | |
545 | ||
546 | * ppc-instructions: Eliminate any uses of labels and goto's. | |
547 | These result in duplicate declarations when a single flat function | |
548 | is being create. | |
549 | ||
550 | * ppc-opcode-jump: New file. Set of opcode rules useful when | |
551 | testing jumping idecodes. | |
552 | ||
553 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
554 | ||

556 | instruction in the function that is doing the decoding. | |

559 | decode functions. | |
560 | ||
561 | * configure.in (--enable-sim-icache): Accept an option list such | |
562 | as 1024,define. Add a new choice to the list - semantic - which | |
563 | will cause igen to generate instruction decode functions that | |
564 | include the corresponding semantic code. | |
565 | ||
566 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
567 | ||
568 | * configure.in: New option --enable-sim-line-nr (default enabled). | |
569 | Enable/disable the inclusion of CPP line directives in the | |

571 | used when generating the simulator code. | |
572 | ||
573 | * Makefile.in (sim_line_nr): Pass to igen. | |
574 | ||
575 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |

578 | available. | |
579 | ||
580 | * configure.in: Adjust to match igen's revamped options | |
581 | ||
582 | Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
583 | ||
584 | * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so | |
585 | that they use the same technique as igen (ie a dummy targets | |
586 | tmp-pk and tmp-hw are created). | |
587 | ||
588 | Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au> | |
589 | ||

674 | core object. | |
675 | ||

1519 | ||
1520 | * device.c (attach_device_interrupt_edge): New. Interrupt model | |
1521 | did not allow interrupts to be wired up as a general net (edges). | |
1522 | Re-implement so that interrupt events can be passed to multiple | |
1523 | controllers and interrupt controllers can further propogate | |
1524 | interrupt events. | |
1525 | ||
1526 | * device.c (attach_device_interrupt_edge) : New, Ditto | |

1547 | ||
1548 | * device.c (external_to_device) : New function that provides a | |
1549 | standard mapping between a devices internal representation (a | |
1550 | pointer) and its external (or what is passed to a client) | |
1551 | representation (a phandle). Implement using the cap object | |
1552 | attached to the root node. | |
1553 | ||
1554 | * device.c (device_to_external) : Ditto | |
1555 | * device.c (external_to_device_instance) : Ditto but for ihandle | |
1556 | and device instance. | |
1557 | * device.c (device_instance_to_external) : Ditto | |
1558 | ||
1559 | * Makefile (device.o): Add dependency on cap. | |
1560 | ||
1561 | * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code | |
1562 | needing to translate between internal and external representations | |
1563 | changed to use the external_to_device et.al. device operations. | |
1564 | * emul_chirp.c (chirp_emul_*) : Ditto | |
1565 | ||
1566 | * Makefile (emul_chirp.o): Remove dependency on cap | |

1569 | ||
1570 | * emul_chirp.c (map_over_chirp_note): Tighten up (and fix) checks | |
1571 | on OpenBoot note section. | |
1572 | ||

1574 | ||
1575 | * emul_generic.c (emul_write_buffer): Use vm faulting byte | |
1576 | read/write calls for buffer transfers. This will cause a fault to | |
1577 | occure if the transfer fails. CHRP catches the fault while the | |
1578 | others suffer the consequences. | |
1579 | (emul_read_buffer): Ditto. | |

1586 | * emul_chirp.c (emul_chirp_create, emul_chirp_instruction_call), | |
1587 | emul_generic (emul_blr_instruction): Use a real blr instruction to | |
1588 | return from a client service call. | |
1589 | ||
1590 | * emul_chirp.c (services): Add all OpenBoot services to table. | |
1591 | ||
1592 | * emul_generic.h, emul_bugapi.c (emul_bugapi_create), emul_chirp.c | |
1593 | (emul_chirp_create) : Use names instead of numbers for | |
1594 | instructions being stored in memory. | |
